SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 248,296, dated October 18, 1881.

Application filed July 18, 1881.

To all whom it may concern: 7

Be itknown that I, ANDREW M. EASTMAN, of Somerville, county of Middlesex, State of Massachusetts, have invented an Improvement in Spring-Beds, of which the following description, in connection with the accompanying drawings, is a specification.

This invention in spring-beds relates to a novel method of supporting the slats in sets of three by means of but two springs. The three slats are joined together by means of a slatconnecting wire, which holds them at the proper distance apart, the hooked ends of the two springs engage the said wire between adjacent slats,and the compoundslats,composed each of three slats, are connected together by means of suitable hooks and eyes.

Figure 1 represents in top view a spring-bed embodying my invention; Fig.2, an end view thereof, and Fig. 3 a detail in side view of one of the springs.

The sides a of the bed-frame are held together by the cross-bars b, whichlatter are provided with suitable wire-bearin g loops, b ,Which receive and support the spring-holder 0, made as a metal rod.

The springs 61 c, employed in pairs, are made from wire bent as shown. The short arm of each spring enters a suitable holein the crossbar I), while its long arm is madeinto a hook, as shown in Fig. 3, to engage the slat-connecting wire g, which latter is of sufficient length to extend through the separate slats 2 3 4 of each compound slat f. Each compound slat is composed of three slats united by the said connecting wire extended loosely through them, the several compound slats to form a bed being joined together by eyes or loops h. The connecting-wire g, wheninserted through the central slat, 3, is straight; but thereafter it will be bent at each side of the slat 3, to form cranks, as shown in the drawings, to prevent lateral displacement of the slats, with which (No model.)

cranks the hooked endsof each pair of springs d c are connected and held, as shown, the connection of the said springs with the wire g being only between the slats 2 3 and 3 4, so that two springs at each end of the bed-frame are made sufficient to support both ends of the three slats united to form a compound slat.

The springs and spring-holdersc are commonly used in spring beds. Making two springs at each end of the frame answer for three slats enables the construction of the bedbottom to be cheapened, and joining the three slats into one by a rigid connection is found to be of advantage, improving the comfort of the person supported thereby.

The eyes permit the slat bottom to be folded compactly for shipping or storage.

With a compound slat composed of t'ourslats I might use three springs at each end.

I claim- 1. A spring bed composed of a number of compound slats,f, each composed of three slats, which are united by a cranked connectingwire, g, the several compound slats being also connected, combined with two springs at each end of each compound slat, and engaging with the said connecting-wires, so as to present at the end of each compound slat fewer springs than there are separate slatsin said compound slats, substantially as described.

2. A series of compound slats, f, composed each of three slats, 2 3 4, united together by the connecting-wires g, cranked, as shown,.

combined with two springs at oneor both ends of each compound slat, and with connecting devices h, substantially as described.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
